You can load the classes dynamically from any path, if you can read the file (class file). The procedure is as follows...
I am giving a simple program which will do this...
public class ScriptExecutionManager extends ClassLoader
public void executeScript(String fileWithPath)
File file = new File(fileWithPath);
FileInputStream fis = new FileInputStream(file);
int available = fis.available();
byte bytes = new byte[available];
Class scriptClass = this.defineClass("Script",bytes,0,bytes.length);
netpod.liveupdate.ScriptInter script = (netpod.liveupdate.ScriptInter)scriptClass.newInstance();
script = null;
scriptClass = null;
// for debugging purpose
public static void main(String s)
